AUTOMATIC GATE.

SPECIFICATION forming part of Letters Patent No. 756,781, dated April 5,1904.

I Application filed December 30, 1901. Serial No. 87,655- (No model.)

To all 1071 0717, it puny concern:

Be it known that I, THOMAS I. DUFFY, a citizen of the United States, anda resident of Chicago, in the county of. Cook and State of Illinois,have invented certain new and useful Improvements in Collapsible Gates;and I do hereby declare that the following is a full, clear, and exactdescription thereof, reference being had to the accompanying drawings,and to the letters of reference marked thereon, which form a part ofthis specification.

This invention relates to improvements in automatic gates, and moreparticularly to that class of automatic gates designed for use oncar-platforms or the like. Heretofore with inventions of this class ithas been common to provide a gate hinged on one side at the end of thecar and adapted to swing inwardly to permit the. passengers to board orleave the car. This type of gate has been objectionable owing to theamount of space required to permit the same to swing inwardlysuflioiently to permit egress from the car and also for the reason thatthe same has been inconvenient to the operatorwhen the car-platforms arecrowded. Another type of gate is a laterally-collapsible gate which maybe telescoped or folded against the side of the car when not in use,occupying little space. Gates of this description when in use owing totheir peculiar construction do not aiford suflicient resistance toprotect the passenger from falling from the car.

The object of my invention is to provide a folding gate of greatrigidity and strength when in use and which is adapted to fold into avery small compass at the end of the car.

The invention embraces means whereby an operator or guard standingpartly on two cars may operate both gates at one and the same time.

The invention consists in the matters hereinafter described, and morefully pointed out and defined in the appended claims.

In the drawings, Figurel is a fragmentary side elevation of a carprovided with a gate embodying my invention. Fig. 2 is a horizontalsection of a car, showing the platform and the gates in plan view. Fig.3 is an enlarged side elevation of the gate, showing the same in itsclosed position. Fig. 4 is a similar view showing the gate in its openposition. Fig. 5 is a vertical section of one of the bearings upon whichthe gate moves.

In said drawings, A indicates a passenger or street car of any desiredconstruction provided at its end with platforms at. Said platforms maybe vestibuled in a familiar manner or may be provided with the uprightsa (1, forming a partial end wall at the extremity of the platform. Thegate is pivoted on the upright or standard a and consists of the upperand lower transverse members B and B, having pivotally secured thereonvertical slats or cross-pieces b. Said slats, as shown, engage at theirends on the outer side of one of the transverse members and the innerside of the other, and between the slats b said transverse members arebent or offset, as indicated in Figs. 2, 3, and 4, to permit the saidslats Z) to pass by and to lie flat against each other, as indicated inFig. 4, when the gate is in its opened condition. Means are provided foropening and closing said gate, as follows: On the ends of the vestibuleor, as shown, se-

cured on the upright a are the rigidly-secured pivot-arms C C, providedwith horizontal laterally-projecting arms or pivots c a, on which aresecured the respective gate members B and B by means of the bell-cranksd (F, one end of each of which is secured to the respective members Band B and the other ends of which project beyond the pivot, as shown inFig. 3, and are pivotally connected with the connecting-rod C at theopposite ends thereof. D indicates a shaft journaled transversely of theplatform on said partial end wall or on the members a a and provided atopposite ends with cranks (Z d, of which that indicated by d isrelatively short and engages the connecting-rod C as indicated in Figs.3 and 4. The other of said cranks, or d, is longer and includes a handlefor manual engagement. Pivoted on the crank d" is alever (Z in positionto be manually engaged when the handle is grasped by the operator andprovided at its inner end with a dog adapted to engage in sockets in thebearings 45 adjacent to said crank and at its outer end with a springcl, engaging on said handle adapted to throw the dog into lockingposition. The sockets in said bearings are so lo cated that the dogengages in one of the same when the gate is in its closed position, asinclicated in Fig. 3, and in another when the gate is in its open.position, as shown in Fig. 4. Means are also provided for securing thefree ends of the transverse members B B on the car ends when the gate isin its closed position. For this purpose socket-pieces E are rigidlysecured to the car end in position to engage the free end of saidmembers. Said socket-pieces open on their upper side to permit saidmembers to fall readily to position.-

Obviously many details of construction may be varied to provideprecision of alinement when dropping the gate into its closed position,and for this purpose, if preferred, each of the bell-cranks may beprovided with an elongated sleeveto engage the pivot-pin 0.

Obviously the gate may be opened on either side the opening, aspreferred,'and many details of construction may be varied withoutdeparting from the principle of my invention.

I claim as my invention 1. A collapsible gate comprising upper and lowertransverse members adapted toextend across the opening to be closed andhaving a series of equidistant bends, a series of connecting memberspivotally secured to said transverse members between saidibends,connected bell-cranks at the inner ends of said transverse members and alever engaging the connection between said bell-cranks.

2. In a gate, an upper and a lower transverse bar having pivoted thereonvertical slats spaced an equal distance apart said transverse bars beingbent and connected on opposite sides of said slats whereby when the gateis elevated said vertical slats and transverse bars are adapted tocollapse laterally and to expand vertically upward.

3. In a device of the class described the combination with an uprighthaving rigidly secured thereon outwardly-extending parallel arms,ofbell-crank levers pivoted on said arms, undulated transverse memberssecured on said bell-cranks, a plurality of slats pivoted on saidmembers between the, undulations thereof, a connecting-rod pivotallyengaging each bellcrank and a crank engaging said connectingrod andacting to collapse the gate laterally permit said slats tolie togetherwhen the gate' is open andspring-actuated means for locking the gate inits closed position and in its open position. i I

5. In a device of the class described the combination in avertically-opening and laterallycollapsible gate, of means for actuatingthegate comprising a shaft, a crank thereonadapted to engageavertically-movable mem' her, a bell-crank pivotally secured on each endof said vertically-movable member and rigidly secured upon the gate, acrank adapted to be manually engaged in operating the gate and aspring-actuated dog acting to hold the gate from movement when in itsopen or closed position.

6., In adevice of the class described the combination with a permanentupright, of parallel pivot-arms rigidly secured thereon, a bell crankpivotally secured on each of said arms, a vertically-movable memberpivotally con-'-'- nected with said bellcranks, an undulated transversemember rigidly secured on each of said bell-cranks and a plurality ofslats pivotally connected with said undulated members each lying out ofthe plane of the other. I

7 A collapsiblegate comprising transverse members provided withaplurality of offsets, a plurality of vertical slats pivotally securedthereto between said offsets, means for operating the gate, said gatelying in the plane of the opening to be closed when in its closedposition and lying in a plane at approximately right angles thereto whenin its open position with the faces of said slats in contact with thefaces of adjacent slats.

In witness whereof I have hereunto sub-- scribed my name in the presenceof two subscribing witnesses.
